I'm usually in bed by 3am. Up for work at 9 or 10. Weekends are all over the place, Friday and Saturday nights can be anywhere from 1am-6am, and Sundays its usually 3am. I usually sleep in til mid-afternoon Saturdays, so I have energy for the night.
Only thing I've noticed from lack of sleep, is that my dreams have become very schizophrenic and I seem to remember them alot more than I used to, they just dont seem to make any sense.

On school days, as long as I can manage up to 6-8 hours of sleep I'm fine, given that I can wake up at least at 5AM so I can go back to sleep. Same for weekends, except no specific time to wake up so I end up sleeping longer

Usually 9-11 PM on weekdays, depending what I'm doing, what sports are on, etc. Weekends, 10PM to midnight.

OMG, get some sleep people...dont go to bed at 6 AM, its not good for you...I get 15 hours of sleep on weekends if I have nothing going on in the morning. Go to bed at 10PM, wake up at 11 AM-1PM. It feels so good.

15 hours every weekend every week? That adds up dude. Waist of life IMO. My sleeping hours range from 6-9.
